According to the invention, a conventional asbestos diaphragm finger type electrolytic cell is advantageously converted to an ion exchange membrane electrolytic cell.

摘要： Electrolysis of an alkali metal chloride solution using an ion exchange membrane is carried out by bringing the anode and the cathode into contact with the surfaces of the ion exchange membrane, whereby electrolysis is conducted at a lower voltage and alkali metal chloride contained in the cell liquor is markedly reduced. In the case of employing a finger type cell, alkali metal chloride in the cell liquor is surprisingly lowered by maintaining the ratio of the effective area of the cation exchange membrane to that of the anode at 1.1 or less. This invention facilitates the conversion of asbestos or modified asbestos electrolysis methods to the ion exchange membrane methods with such ease that the quality of the products is not only enhanced but the serious problems of environmental pollution due to asbestos are solved.
